The ISL70321SEH radiation hardened quad power supply sequencer evaluation boards highlight an innovative turn-on and turn-off sequencer solution for multi-voltage space-based applications using point-of-load (POL) DC/DC voltage converters. The ISL70321SEHEV1Z platform provides a single IC 4-event evaluation platform, whereas the ISL70321SEHEV2Z provides a dual cascaded IC 8-event evaluation platform. Both evaluation boards are provided on the same PCB design and are both available from inventory in the desired configuration.

Features

  • Jumper enabled for stand alone or POL evaluation
  • Convenient power connection
  • Done indicator
  • Easy interconnectivity with other Intersil boards

Videos & Training

16 of Intersil radiation-hardened ICs were onboard the December 5, 2014 maiden voyage of NASA's Orion spacecraft, also known as the uncrewed Exploration Flight Test 1. These rad-hard ICs are deployed in Orion's crew module, where they are used to support subsystems for mission critical applications in power distribution, navigation and flight control, and in the inertial measurement unit.
